Here's one I did a while ago that can also be found in my
gray set.
It's a T with an oil well inside it on my usual gray background.
Edit - Alright, I uploaded and attached the logo here. How on earth can I tell if it's actually in the post? This is the first time I've tried attaching an image since the board changeover.
You can always just download that entire set, it should be in there.
